Neural Networks Group

The cortex is the largest part of our brain, and its function remains a major mystery in neuroscience.  We are only beginning to understand its role in crucial brain functions, such as learning and memory. Our group explores how the cortical neurons, and their dendrites, encode and process information during behaviours. By examining individual neurons and the networks that drive behaviour, we aim to uncover changes that occur in both normal brain function and dysfunction, with a particular focus on brain cancer.

About our research

Individual neurons are continuously bombarded with thousands of synaptic inputs onto their dendritic branches. We investigate how the brain processes this information by measuring the activity of neurons within the neocortex using a variety of techniques including two-photon calcium imaging and patch-clamp electrophysiology.

Our research specifically focuses on neuronal dendrites, the thin neural processes that actively transform synaptic inputs into neuronal output. The dendritic integration of synaptic input, its modulation and its influence on brain function and behaviour is the focus of our research.

Through our work, we not only aim to reveal how sensory information is received, transformed and modulated in neurons but also how modulation of synaptic integration contributes to the overall neural network activity underlying learning and memory.

Brain cancer is one of the most devastating diagnosis a patient can receive. Unfortunately, despite significant research efforts, survival rates have changed little in the past 40 years and further research is required to understand this devastating disease. Our laboratory aims to contribute to our growing understanding of how neural activity influences the proliferation of brain cancer.
